I don't remember the exact numbers, but early on in this poll, the votes were very heavily weighted toward the bottom half. I feel like my vote (5-8) was the only vote in the top 12 after a pretty decent sampling of votes had come in. Interesting to see the distribution now. I wonder how much of that was just due to the early sample being a poor representation of the remaining votes that were yet to come in (maybe they counted the votes in Dallas, TX, first

), and how much of that is votes that were actually changed.
I don't think you can change your vote. If so, I think he would be much higher right now.
It's tough to really rank a coach as so much has to do with the players on the field. You can watch Brady throw and see talent, skill, mechanics and judge him based on that.
Sure you can judge a coach on if you think his decision to go for it on 4th was a good one, but that result is still usually determined by how good of a throw that QB made on 4th down (as an example)
